Go to http://www.insanelymac.com/ and start you're research (call it a
hobby).
Yes, now you can run OS X on intel P4 CPUs with SSE2, and on AMDs
using the voodoo kernel. However, getting QE and CI is another story;
it depends on your video card and controllers. Also sound and
networking usually require tweaking certain kexts or adding ones that
Apple doesn't have depending on your board and bridges. You've got to
build or find an iso compatible with you're setup if you want to do a
retail install on a P4 or choose a ready made distribution (not retail-
not vanilla) that will work on your machine.

In July I followed Peter and built a shuttle SG31G2 specifically with
a retail install of Leopard in mind while buying the CPU, memory,
drives and video card. = Strong stable machine now running 10.5.6.
After that experience I went down the other road and fooled, fiddled
and tweaked a retail install onto a HP P4 1.6ghz with 768 ram. Updated
via delta to 10.5.6! It does NOT have QE or CI enabled, but I must say
for that old machine it runs pretty damn well.

Which will offer me the most expandability and speed?
The $20 1.8ghz Dell will most likely NOT out-perform a G4, but by
carefully building your own machine, which is what Peter suggested a
Hackintosh can keep up with a MacPro.

the Second CPU will double the speed of your Mac,
but the slower Frontside Bus (100 MHz vs 133MHz) is the slower
bottleneck, your data will have to squeeze through.
a 533MHZ G4 Single PowerMac with a 133MHZ bus, is great for one/few
programs.
but a 500MHZ G4 Dual PowerMac with a 100MHZ bus, is decent for many
programs,
but the faster Frontside Bus will speed up the mac,
another help is more RAM, preferable 1GB or more.
another help would be a APG video card with 128 / 256 MB VRAM. more
VRAM is faster.

Incorrect.

A second CPU does not 'double the speed' of any machine.

Per http://www.devx.com/go-parallel/Article/27399:

With current dual processor arrangements single threaded apps are 
expected to see a 10% increase in performance whereas multi threaded 
apps are expected to perform better by at least 40-80% over a 
uni-processor configuration for a majority of applications.

This assumes that the apps that send a thread over to a CPU are able to 
access the needed data without wait (think disk I/O).


 but the slower Frontside Bus (100 MHz vs 133MHz) is the slower
 bottleneck, your data will have to squeeze through.

Yes, the FSB is a bottleneck, but the difference between 133 and 100 is 
not that great, nor would be the performance increase.  Sure, the RAM 
bus is 33% faster, but the PCI bus isn't any faster.


 another help would be a APG video card with 128 / 256 MB VRAM. more
 VRAM is faster.

Not always, and generally only when playing 3D games.  The card slot is 
still stuck at the same speed as the original card when upgrading.  Any 
acceleration functions on the video card chipset, or the chipset being 
faster all together, go more toward speeding up the graphics subsystem 
than adding more RAM to the video card.

 Hands down, the machine with the faster bus.

  When Apple redesigned the G4s for the faster bus, they also wanted to
  increase the number of PCI slots, so one of the RAM slots had to go.

  The result was the Digital Audio series (which includes the

  The LBA48 property can be added to all of these, anyway, so there

  Should you consider a faster processor, and you really should, get
  one which is designed for both 100 and 133 MHz buses.

  But, for that money, you could build an Intel-based Hackintosh, which
  could easily out-perform any G4 Mac by 5-to-1.

If I assume that the amount of free RAM when either machine is running
the server applications you need is about a quarter to a half a gig,
and I assume some other factors, then I'd say...

If you plan to run many processes on the server the dual cpu G4 is
likely your best bet.

If you plan to run few processes on the server the single cpu G4 will do fine,
